' WIEATHTERPROOF PASTE.

. Specification of Letters Patent.

Patented June 12, 1906.

Application filed February 6, 1906. Serial No. 299,824

To all whom it may concern.-

- -Be it known that I, MATHIAS HENNEN, of

Minneapolis, Hennepin county, Minnesota,

have invented certain new and useful Improvements in Weathe roof Paste, of which a the following is a s ec cation.

In the erection of a building it is customary to use s me kind of paste filling material around-the windows between the buildin 1 wall and the stafi-bead to prevent the coFd air and dust from enterin the building around the window-frame. he material ordinarily employed as a filling for this crack or crevice has been found to be unsatisfactory,

r 5 as it will shrink away from the building-wall and from the bead, thereby opening the joint, and will frequently crack and fall out of the joint altogether. Various substances have been employed in an attempt to remedy'this 2o defect; but all of them, as far as I know, have been for one cause or another unsuitable and unsatisfacto Most of the materials e ployed will s and crack when ex sed to the weather, as'above described, and none of them will remain intact in all temperatures and form a perfect seal between the bead and the wall.

The object therefore of my invention is to provide a plastic substance which when filled into the oint between the staff-bead and wall of a bui.ding will adhere to the surfaces on' each side and upon becoming hard will not crack or shrink away from the wall and the bead and expose the joint to theentrance of 3 5 cold air or dust anddirt.

A further object is to provide a plastic substance which will be absolutely weather-' proof and having once become set in the joint will remain so permanently regardless of the 40 varying degrees of temperature to which it may be exposed.

y invention consists generally in the com position of ingredients, as described, and pointed out in the claims.

In carrying out my invention I have found that to produce the best results the following materials should be used in the proportions ,named: putty, five one-fourth pound varnish, two ounces; raw

5o linseed-oil, two ounces; butter of antimony,

pounds; pumicestone,

one ounce; japan, two ounces; turpentine, one ounce; acetic acid,- one ounce. These ingredients are all mixed and kneaded together into a plastic mass, and when the materials have been thoroughly mixed an oily creamy substance Will collect on the surface, which will adhere to the walls of the joint and render it impervious to the passage of moisture, dust, or air. The material when placed in the joint and exposed to the weather will harden slowly, but on becomin thoroughly set will be almost as firm and rigid as-the surfaces to which it adheres. Any suitable coloring-matter may be used in the 1paste, according to the color of the bui where it is used.

The pa ate in addition to its use in connection with the joints around a window-frame may be em loyed in the setting of skylights, sidewalk-b ocks, or tiling, or wherever it is necessary or desirable to employ a plastic substance which will not shrink or crack when exposed to the weather and will be air and moisture proof. V

The proportions of ingredients herein speci- 7 5 may of course, be varied without departing from the spirit of my invention, and equivalent substances may be employed for some of the ingredients-used.

I claim as my invention- 8o 1. The herein-described weatherproof composition consisting of putty, pumice-stone, varnish, raw linseed-oil, butter of antimony, japan, turpentine, and aceticacid.

2. The herein-described weatherproof composition comprising utty, powdered stone, varnish, oil, butter 0 antimony, turpentine, acetic acid, and'a drier.

3. The herein-described weatherproof composition consisting fputtyfive pounds, pum 9o ice-stone one fourth pound, varnish two ounces, raw linseed-oil two ounces, butter of antimony one ounce, japan two ounces, turpentine one ounce, and acetic acid one ounce.

In Witness whereof I-have hereunto set my hand this 31st day of J anuary, 1906.
